WHAT IT DOES

What ticktick_complete_task does on Ticktick

AI agents use ticktick_complete_task to create or update resources in Ticktick — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ticktick environment.

WHY IT NEEDS A POLICY

Why ticktick_complete_task needs a policy

This tool creates a reversible modification to task data (completing/uncompleting status), placing it in the Write category rather than Destructive. The severity is medium because completing a task in a task management system can affect workflows and deadlines, but the action is reversible (tasks can typically be reopened).

From the tool's definition Tool description states "mark a task as done" which modifies task state; requires projectId and taskId parameters to perform the update action.
